Internal Battery Resistance
{"Image DocumentName": "Internal Battery Resistance", "Image ImageDescription": "If the internal resistance is zero, the terminal voltage equals the emf. In a real battery, there is internal resistance, r. The terminal voltage, DV = e \u2013 Ir. Use the active figure to vary the emf and resistances and see the effect on the graph.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
